With luck
About 10% of wildlife watchers report a Yellow-Vented Hornet sighting in Sapporo on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 33rd most-seen of the 44 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Yellow-Vented Hornet in Sapporo on a given day, against under 5% in July and October–April, the lowest months. Those are among Sapporo's wettest months, with about 150 mm of rain a month against 60 mm in April.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yellow-Vented Hornet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 11
Of the 11 cities where we can rate Yellow-Vented Hornet sightings, Sapporo ranks 6th at about 10%. The best odds are in Nagoya (Japan, about 20%), Yogyakarta (Indonesia, about 10%) and Sendai (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow-Vented Hornet is recorded against all the insects logged in Sapporo (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
